The first approach was to implement a function that sents a string to the OSM API directly, using http. The API then returns spatial coordinates in json-format. The second approach was to use the […]

In that example I implemented a function that sends locations as strings to a Open Street Map API and then receives latitude and longitude coordinates as return values in JSON-format. In this post I will […]
In this post I want to provide a brief overview of useful packages in R for visualizing spatial data in R.
